FREDERICK J. H. HAZARD, OF TORONTO, ONTARIO, CANADA.

WIRE CASH-CARRIER.

Application filed October 12, 1915.

To all whom it may concern Be it known that I, FREDERICK J. H. HAZARD, of the city of Toronto, in the county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in Wire Cash-Carriers, of which the following is a specification.

This invention relates to cash carrier systems of the type in which a car runs on two wires, the car being propelled by spreading the wires behind it. In such systems the wires are subjected to heavy strains, as the act of spreading them, as such systems ar usually constructed, tends to increase the distance between the opposite ends of the wires, and the wires will sometimes break.

My object therefore is to devise means for easing the strains on the wires and to secure a more elastic application of the propulsive power.

I attain my object by providing resilient yielding means to ease the strain on the wires and preferably by connecting thelevers at one end of the system to the anchorage through the medium of a spring draft connection, so that the wires which are connected to the levers are held taut by the tension of the springs.

The whole is constructed in detail substantially as hereinafter described and as illustrated in the accompanying drawings in which Figure 1 is a side elevation of one terminal of a wire cash carrier system provided with my improvements; Fig. 2 a similar view showing the same applied to another form of terminal; and Fig. 3 an end view of the parts shown in Fig. 2.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

In cash carrier systems employing two wires, it is common to employ as terminals either two such as disclosed in Fig. 2 or one such as disclosed in Fig. 1 and one as disclosed in Fig. 2, dependent on whether the lines are level or on a grade.

Referring particularly to Fig. 1, 1 is part of the anchorage of the terminal. 2 is a member to which the lever system is pivotally connected. In Fig. 1, 3 and 4: are levers, each pivotally connectedto the member 2. The wires 5 and 6 are connected to the ends of these levers as shown. The upper lever carries a receiving guide 7 for the car (not shown), and the other lever 4 a buffer 8. These parts Specification of Letters Patent.

are of ordinary construction. The levers in this form are spread by means of the lever handle 9, the lower end of which may be gripped by the hand. This handle is pivotally connected with the lever t and engages the under side of the lever 3.

The member 2 is connected with the anchorage by means of spring draft rigging constructed substantially as follows: Secured to the end of the member 2 are one or more rods 10. These rods slide through a block 11 connected with the anchorage. Preferably the connection is pivotal as shown so that the draft of the wires will always be approximately axial of the rods. On the outer ends of the rods coil springs 12 are placed, which bear against the block 11 and against the movable collars or other abutments 13 secured to the ends of the rods. The springs are under compression so that a tension is constantly maintained on the member 2, and therefore on the wires 5 and 6. I find that it is preferable to employ a plurality of rods and springs, as the strain is better distributed and there is less likelihood of jamming as the effect of the action of side strains.

In the construction shown in Fig. 2, the lever system is slightly different, having only one pivotal connection with the member 2, but as the levers are pivoted together at 14, the elastic cushioning effect of the spring draft rigging affects both wires. In this form the member 2 is yoke shaped, as shown particularly in Fig. 3, so that the upper lever 3 may occupy approximately the horizontal position shown. The block 11 is also similarly shaped and the rods 10 are necessarily grouped at opposite sides of the yoke. In all other respects the construc tion is substantially the same. As the levers for spreading the wires necessarily swing on fulcrums, an end strain is put on the wires, over and above what is necessary in efi ecting the propulsion of the car. This end strain is in my construction satisfactorily taken up by the springs 12. In some cases a spring draft rigging 16 may be employed in the back stay or stays 15 of the terminal. As a standard of some length is usually employed in the anchorage of the terminal it will yield sufficiently without detriment to permit of the efficient action of the draft rigging. This form, with the resiliency provided between the anchorage and its support, may be used either with or without the spring draft rigging betweenthe lever system and the anchorage.

I find that with my device not only is the breakage of the wires prevented, but that the operation is easier and more elastic, and that it is possible to spread the wires to a greater extent, thus increasing the propelling force and increasing the range of the system.

hat I claim as my invention is:

1. In a cash carrier system employing two wires, the combination of an anchorage; a lever system to which the wires are connected; a member to which the lever system is pivotally connected; and a spring draft rigging between said member and the anchorage.

2. In a cash carrier system employing two wires, the combination of an anchorage; a lever system to which the wires are connected; a member to which the lever system is pivotally connected; a rod secured to the end or" said member; a block connected with the anchorage and through which said rod slides; a coil spring on said rod hearing at its inner end against said block; and an abutment at the outer end of said rod against which the other end of said spring bears.

3. In a cash carrier system employing two wires, the combination of an anchorage; a lever system to which the wires are connected; a member to which the lever system is pivotally connected; a rod secured to tie end of said member; a block pivotally connected with the anchorage and through which said rod slides; a coil spring on said rod bearing at its inner end against said block; and an abutment at the outer end of said rod against which the other end of said spring bears.

i. In a cash carrier system employing two wires, the combination of an anchorage; two levers to similar ends of which the wires are connected, the other ends of the levers being pivoted together; a yoke-shaped member to which one of the levers is pivoted, the said member normally straddling the lever; a plurality of parallel rods secured to the end of said member; a block connected with the anchorage and through which said rods slide; coil springs on said rods bearingat their inner ends against said block; and abutments at the outer ends of said rods against which the other ends of said springs bear.

5. In a cash carrier system employing two wires, the combination of an anchorage; two levers to similar ends of which the wires are connected, the other ends of the levers being pivoted together; a yoke-shaped member to which one of the levers is pivoted, the said member normally straddling the lever; a plurality of parallel rods secured to the end of said member; a yoke-shaped block connected with the anchorage and through which said. rods slide; coil springs on said rods bearing at their inner ends against said block; and abutments at the outer ends of said rods against which; the other ends of said springs bear.

6. In cash carrier system employing two wires, the combination of an anchorage; a lever system to which the wires are connected; a member to which the lever system is pivotally connected; rods secured to the end of said member; a block pivotally connected with the anchorage and through which said rods slide; coil springs on said rods bearing at their inner ends against said block; and abutments at the outer ends of said rods againstwhich the other ends of said springs bear.

In a cash carrier system employing two wires, the combination of an anchorage; a lever system connected to the anchorage and the wires and adapted to spread the latter; a spring tension device; and connections between said tension device and both wires whereby said device simultaneously tensions both wires, said tensioning device being adapted to yield to relieve the extra strain put on the wires when the wires are spread.
